This paper illustrates how the size and type of substituent R in the phosphinate group of ferrocenyl bisphosphinic acids can affect conformational possibilities and coordination packing. It also demonstrates that H -phosphinate plays a key role in variational mobility, while Me- or Ph- substituents of the phosphinate group can only lead to 0D complexes or 1D coordination polymer. Overall, this paper provides valuable insights into the design and construction of coordination polymers based on ferrocene-contained linkers. It sheds light on how different reaction conditions and substituents can affect conformational possibilities and coordination packing, which could have significant implications for developing new polymers with unique properties.

Differentiation between benign, primary and secondary malignant tumors is a critical problem in the clinical treatment of adrenal tumors, especially in patients with isolated adrenal lesions. In most cases, the correct diagnosis can be established microscopically with standard staining with hematoxylin and eosin. However, there are cases when it is almost impossible to distinguish metastasis from primary adrenal cancer, so an accurate diagnosis requires an immunohistochemical examination.This article presents five unique observations of secondary adrenal tumors that were diagnosed by us in the current surgical material: metastasis of clear cell renal cell carcinoma, follicular variant of papillary thyroid cancer, metastasis of keratinizing squamous cell carcinoma of the cervix, lymphoepithelioma-like carcinoma of the bladder, as well as malignant mesothelioma. Taking into account the extreme rarity of the presented observations, we present an analysis of the literature data.

Herein, the synthesis of ferrocene-containing salts is presented. Acylation of ferrocene (Fc) according to the Friedel-Crafts method led to ω-bromoacyl ferrocenes. The ω-bromoacyl ferrocenes were subsequently introduced to quaternization reaction with tri- tert -butyl phosphine, which resulted in phosphonium salts. Obtained phosphonium salts were characterized by physical methods. The electrochemical properties of phosphonium salts were studied by cyclic voltammetry (CV). It was found that the replacement of n -butyl fragments at the phosphorus atom by tert -butyl leads to a more anodic potential shift. In contrast to isolobal structures Fc-C(O)(CH 2 ) n P + ( n -Bu) 3 X - and Fc-(CH 2 ) n+1 P + ( n -Bu) 3 X - , the CV curves of Fc-C(O)(CH 2 ) n P + ( t -Bu) 3 X - and Fc-(CH 2 ) n+1 P + ( t -Bu) 3 X - did not show a large discrepancy between forward and reverse currents. The transformation of the C=O groups to CH 2 fragments had a significant effect on the electrochemical properties of ferrocene salts, the oxidation potential of which is close to that of pure ferrocene.

The article reveals little-known scientific data on the traditional risk factors of cardiovascular diseases in relation to social groups of the elderly, old people and centenarians. Some of metabolism associated signs of ageing are considering. In the article some biochemical markers in seniors are evaluated (lipids, fibrinogen, uric acid etc.). Some particularities about atherosclerotic lesions of coronary arteries in seniors are discovering, as well as relationships between coronary heart disease (CHD) and fatty liver degeneration. One more topic of the article is the lipid spectrum characteristics in senior patients with different types of heart diseases and psychological features and behavioral personality types of the seniors with cardiovascular pathology. Special attention payed on so-called preventive paradox in men older than 60 years with different forms of CHD, when the influence of traditional risk factors is critically decreased, and as important prognostic factors low levels of high-density lipoprotein cholesterol, reduced APO-A1, an increasing of APO-B/APO-A1 ratio and low physical activity play a significant role.

The present paper reports a clinical case of local syphilitic meningoencephalitis known as Argyll-Robertson syndrome and manifested in the form of acute sensorineural loss of hearing. The patient was a 46 year old resident of the city of Irkutsk. He experienced the sharp impairment of hearing involving both ears with the accompanying feeling of dizziness, disturbed orientation of the locomotorbehaviour, the lurching gate, subfebrility, the loss of the ability to speak and write. The diagnosis was based on the presence of anisocoria, the absence of consensual pupillary reaction to the light, weak atropine action on the pupils, well expressed positive results of the VRDL (blood) and RW (liquor) tests, an enhanced signal from the left temporal region in the T-2 regime during MRI, positive hearing dynamics within 12 hours after the onset of anti-inflammatory, antibacterial and infusion therapy. The specific feature of the clinical case being considered is differential diagnostics was performed with the purpose of distinguishing it from otogenic brain abscess associated with chronic left-hand mesotympanitis.

The circadian clock controls many circadian outputs. Although a large number of transcripts are affected by the circadian oscillator, very little is known about their regulation and function. We show here that the Drosophila takeout gene, one of the output genes of the circadian oscillator, is regulated similarly to the circadian clock genes Clock (Clk) and cry. takeout RNA levels are at constant high levels in Clk(JRK) mutants. The circadian transcription factor PAR domain protein 1 (Pdp1epsilon) is a transcription factor that had previously been postulated to control clock output genes, particularly genes regulated similarly to Clk. In agreement with this, we show here that Pdp1epsilon is a regulator of takeout. Takeout levels are low in flies with reduced Pdp1epsilon and high in flies with increased amounts of Pdp1epsilon. Furthermore, flies with reduced or elevated Pdp1epsilon levels in the fat body display courtship defects, identifying Pdp1epsilon as an important transcriptional regulator in that tissue.

Mating behavior in Drosophila depends critically on the sexual identity of specific regions in the brain, but several studies have identified courtship genes that express products only outside the nervous system. Although these genes are each active in a variety of non-neuronal cell types, they are all prominently expressed in the adult fat body, suggesting an important role for this tissue in behavior. To test its role in male courtship, fat body was feminized using the highly specific Larval serum protein promoter. We report here that the specific feminization of this tissue strongly reduces the competence of males to perform courtship. This effect is limited to the fat body of sexually mature adults as the feminization of larval fat body that normally persists in young adults does not affect mating. We propose that feminization of fat body affects the synthesis of male-specific secreted circulating proteins that influence the central nervous system. In support of this idea, we demonstrate that Takeout, a protein known to influence mating, is present in the hemolymph of adult males but not females and acts as a secreted protein., Competing Interests: Competing interests.
